The resolving power of telescope of aperture 100cm for light of wavelength 5.5×10−7m is ...............1.49×107149×10714.9×1070.149×107

The correct option is A 0.149×107Aperture (diameter) of telescope D=100cm=1m Wavelength of light λ=5.5×10−7mResolving power of telescope RP=D1.22λ⟹ RP=11.22×5.5×10−7=0.149×107

The resolving power of telescope of aperture $100 c m$ for light of wavelength $5.5 \times 10^{- 7} m$ is ...............
$1.49 \times 10^{7}$
$149 \times 10^{7}$
$14.9 \times 10^{7}$
$0.149 \times 10^{7}$

The correct option is A $0.149 \times 10^{7}$
Aperture (diameter) of telescope $D = 100 c m = 1 m$
Wavelength of light $λ = 5.5 \times 10^{- 7} m$
Resolving power of telescope $R P = \frac{D}{1.22 λ}$
$⟹$ $R P = \frac{1}{1.22 \times 5.5 \times 10^{- 7}} = 0.149 \times 10^{7}$
